我用brew命令安装了rustup，但仍然说找不到rustup命令。我不确定我是否缺少任何安装步骤。任何帮助，将不胜感激。

尝试编译：https://github.com/SergioBenitez/Rocket/tree/master/examples/hello

Cargo.toml

[dependencies]
rocket = "0.4.10"

抱怨我每晚都需要 Rust

$ cargo build
...
  Error: Rocket (core) requires a more recent version of rustc.
  Installed version: 1.54.0 (2021-05-17)
  Minimum required:  1.54.0-nightly (2021-05-18)

我已经完成了本地目录覆盖

$ rustup override set nightly

我每晚运行 2021-05-17 但我需要 2021-05-18

$ rustup show
...
active toolchain
----------------

nightly-x86_64-unknown-linux-gnu (directory override for '/<redacted>')
rustc 1.54.0-nightly (3e99439f4 2021-05-17)

我尝试了各种命令来获取更新的每晚

$ rustup update
$ rustup update nightly
$ rustup toolchain install nightly-2021-05-18

当我这样做的时候，会发生一些奇怪的事情rustup update nightly

$ rustup update nightly
